Acapella Celesta MK II mit ION TW 1S Hornlautsprecher


Top gepflegte Acapella Celesta MK II Hornlautsprecher mit  ION TW 1S Plasmahochtöner, der unter anderem auch in der  Sphäron Excalibur Verwendung findet. Die Frequenzweiche wurde für 2000€ beim Spezialisten "Klangmeister Audiolabor" mit hochwertigsten Komponenten einer Frischekur unterzogen und spielt seitdem besser als bei Markteinführung. Die Verkabelung der Acapella wurde durch Reinsilberkabel erneuert. (ebenfalls Audiolabor). Der Plasmahochtöner / Ionenhochtöner ION TW 1S wurde neu beim Hersteller Acapella für viel Geld Überholt zur Revision und befindet sich wieder im Neuzustand.


Das Paar Corona Plasma Hochtöner alleine kostet heute bei Acapella 10.000€!

ACAPELLA ION TW 1S (Ionic Tweeter)


The Acapella ion tweeter „Ion TW 1 S“ is a perfected and sophisticated loudspeaker chassis, whose exceptional performance and qualities can only be enjoyed completely if used properly.


It was designed to reproduce the harmonics of the music as detailed as possible. To reach this goal, a design with the smallest possible mass had to be developed. Relative to its function the Acapella ion tweeter has no mass! To carry out this project, a very unusual kind of design had to be created.


High voltage within the unit produces a constant arc. This arc is modulated with the musical signal (flame oscillates with the time of the music). This is the reason why the number of electrons within the arc varies. A larger or smaller amount of electrons requires similar space. Due to this variable need of space the surrounding air molecules have to dodge the more or less quickly. This evasive action or bumping of the air molecules generates over-, resp. underpressure and, therefore, sound. In this way, the Acapella ion tweeter is able to reproduce sound without membrane and without mass

Regarding transient capabilities and phase stiffness, the obtained sound quality cannot be realised by using conventional tweeters. Comparing the ion tweeter with other tweeter systems, its unobstrusive sound image will attract you. This kind of reproduction is to be attributed to the lack of harmonic and transient distortions.
